appeared in a window in one of the building’s precincts.
The ghosts of a monk and a stone mason who also supposedly died there have been spotted as well.
The city’s Cowgate area is believed to be haunted following an incident of body snatching back in the 1820s.
Mr Orme added: “Although the museum is currently closed to the public we still have staff working here and some of those have heard mysterious footsteps when nobody else was around.
“There have been several ghost sightings at the Queensgate Shopping Centre over the past 30 years.
“The centre is built on an old residential area which used to contain shops and homes so people say the ghosts could be former residents there.”
So why are people so fascinated by ghost sightings and what should they do if they experience one?
Mr Orme said: “Ghost sightings capture people’s imaginations because they are linked to our fascination about what happens after death.
“I have met people who claim to have seen ghosts and some of them are the most down-to-earth rational men and women you could ever meet.
“But when they start telling you about the ghost they saw their belief is completely rigid and no amount of reasoning can change their minds.
“At the end of the day people are suckers for a good ghost story – even those who don’t believe in ghosts – and that’s never going to change.”
